Because i do! It has very high DT (16) , is very light , and cheap to repair. I love it and it is always my first choice.

By the time I explored Vault 34 I'd completed Honest Hearts and had Joshua Graham's armour so didn't take it. Had enough issues with carryweight trying to carry out all the guns from the armoury. A similar option was the Sierra Madre security armour, but I preferred the Assassin suit.
